An early morning, bullet train, local train and ferry—these are the ingredients of Rabbit Island haikyo. Rabbit Island, officially known as Okunoshima, is a small island about 50km from Hiroshima in the Seto Inland Sea. It’s a warm and fuzzy place, covered in hundreds maybe even thousands of rabbits. Nearly all natural predators were killed off in the late 1920s. Why, you may ask? Well to build a top secret government run poison gas manufacturing compound of course!
Mustard gas, lewisite and other poison gases were manufactured and stored on Okunoshima between 1929 and 1944. Although Japan signed the 1925 Geneva Protocol prohibiting the use of biological and chemical weapons, it didn’t necessarily ban the development of such weapons. Sadly, Japan still did use chemical weapons, many of which probably came from Okunoshima, to kill an estimated 80,000 Chinese soldiers. Of course this was, and in some ways still is, hush-hush. The very existence of Okunoshima was wiped from maps, history books and ultimately forgotten until 1988, when a museum opened on the island. Long story short, the history of Okunoshima is much more sinister than its current incarnation as the loveable and cute Rabbit Island.

Naturally, I came for the ruins of an incredulous past rather than for fluffy bunnies. I like rabbits well enough, but wouldn’t travel many hours across Japan to pet them for a weekend. Surely, there is nothing wrong with those who do though. I’m more concerned about myself who is drawn to rotting concrete, rusted metal and less than wholesome fun.
I had two days on the island with three of my friends. If you spend the night on the island you have two options—stay at the hotel or camp. We chose the latter, a fenced off patch of grass. The fence is theoretically used to keep the rabbits out, I say theoretically because it doesn’t. Rabbits are everywhere and will get into your fried rice mix if you don’t take drastic measures such as hanging your food in a bag from a tree.
After renting some awesome electric-assist bicycles, a friend and I decided to circle the island and check out a few of the ruins dotting the island. Most of the ruins are fenced off and easily accessible to other tourists making it difficult to actually enter them. It was not such a big deal though, since most of the structures have been cleared out and there is very little left behind in terms of personal relics.
Since the island was a military installation, there were a few bunker compounds scattered about the island. Again, there was not much to be seen but the concrete shells that sheltered the inhabitants of the island.
Zooming around the island on the bikes was definitely a treat. For the most part, motorized vehicles are prohibited on the far side of the island. On the high roads you can look out over the Seto Inland Sea and catch a cool sea breeze. On a small road my friend and I spotted a huge snake, possibly the luckiest snake in Japan if it likes rabbits! Looks like all natural predators were not exterminated after all.
Soon after spotting the snake, we turned down a small footpath to one of the more interesting haikyo on the island, MAG1. MAG1 was a gunpowder magazine built of red brick. The roof was built out of tile which collapsed to now make the floor covered in overgrowth.
After circling the island we decided to meet up with two of our other friends to check out the most famous haikyo on the island, the power station that supplied electricity to the gas manufacturing plant. Picturesque but not overly exciting with the sun setting, we decided to move on to the last crumbling edifice.
The gas storage facility—a crumbling concrete arch with a stunning view. Personally, this was possibly my favorite ruin on the island, because you could look out onto the Seto Inland Sea. Standing inside the structure was a bit chilling, knowing that it once housed tons of gas and future death sentences.
At night we had a wonderful camp dinner after a day of exploration. The next morning was for the rabbits. After a few hours with them, I certainly preferred ‘Rabbit Island’ over ‘Okunoshima’. The ruins themselves are not overly impressive unlike their gruesome history. The rabbits on the other hand were overwhelming in both number and kawaii*.
